If the big bang theory is an explanation on how the universe was created, then what existed before the big bang occurred? Veuer’s Sam Berman has the full story.

Famed physicist Stephen Hawking definitively answered one of humankind’s grandest questions — What was around before the Big Bang?

“Nothing was around,” Hawking told astrophysicist Neil deGrasse Tyson on his show StarTalk.

Saying he uses a “Euclidean approach to quantum gravity to describe the beginning of the universe,” Hawking goes deep into what that actually means. A degree in astrophysics will help you understand, but he makes a concise point about the Big Bang, which happened nearly 14 billion years ago.

“The Euclidean space-time is a closed surface without end, like the surface of the Earth,” he said. “One can regard imaginary and real time as beginning at the South Pole, which is a smooth point of space-time where the normal laws of physics hold. There is nothing south of the South Pole so there was nothing around before the Big Bang.”
